As a management type, I'd rather my people be devoted to the cause. Discipline will slip on occasion; that's fine, that's the way the world works. We can work on that. What we cannot do is create motivation for people beyond a certain extent of incentives and disincentives. People have to choose to be determined, to strive for the common cause, and if they make that decision they're tremendously valuable.

I suppose from my own perspective determined has generally been better. I've worked with quite a few people who while disciplined were essentially incapable of planning for the future and increasing efficiency. Determined people can be a drag for monotonous tasks but determination can allow for a degree of self discipline

My view is that determination is the most preferable of the two. Whilst discipline might more often be a more efficient way to get things done, I do think that determined people who lack discipline end up failing that which they do not like, despite their determination, which forces them to find out what they're passionate about, for which they do not need discipline, which means that the determination will take you as far as you want it to. I think it more often leads to a more enjoyable life.

For those of you who choose discipline: Remember, the scenario is not only that the determined person lacks discipline, but also that the disciplined person lacks determination. I personally wouldn't want to live a life without determination
